6 Claims. (Cl. 12S-268) ABSTRACT OF THE DISCLOSURE An adhesive bandage having a container of liquid medicament of a predetermined unit dose exposable for saturating the bandage pad with fresh medicine at a selected time just prior to use.

This application is a continuation-impart of my earlier application Ser. No. 343,023, led Feb. 6, 1964, now United States Patent No. 3,297,032, issued J an. 10, 1967, entitled, Adhesive Bandage Having Container of Medicament Carried by Removable Protector Strip.

The invention relates to improvements in adhesive bandages and is particularly concerned with the construction and assembly of adhesive bandages having medicament integrally associated therewith. Heretofore, adhesive bandages have been impregnated with medicament, but have had limited medicinal effect owing to the medicament becoming stale through deterioration or evaporation of some or all of its ingredients. Certain medicaments must have moisture to be eifective, and others become caustic or otherwise ineffective when 'subjected to atmosphere for more than critical lengths of time. In the use of some medicaments, unit dose is critical inasmuch as overdose is not only wasteful but also can result in irritation or injury and under-dosage in ineffective.

With the foregoing factors in mind, applicant has provided the herein disclosed bandage with a medicament which is integrally connected to the bandage and which is sealed in fresh form protected from atmosphere prior to its being released at the time of use, in a unit dose of predetermined amount, in original intended potency. The medicament can be a salve or a fluid.

It is therefore Ian object of the invention to provide a novelly constructed medicated bandage.

Another object of the invention is to provide an adhesive bandage with a novel container for medicament which is capable for use in an efficient manner by delivering the medicament at its intended strength to the wound.

Another object is to provide a medicated bandage 'which is not difficult or expensive to manufacture, is easy to'apply and capable of delivering medicament to the area to be treated at the intended strength of the medicament, notwithstanding most conditions of storage of the bandage prior to use.

The structure by means of which the above noted and other advantages and objects of the invention are attained will be described in the following specification, taken in conjunction with the accompanying drawings, showing preferred illustrative embodiments of the invention, in which:

FIGURE 1 is a perspective view of an adhesive bandage embodying the features of the invention having a pouch containing medicament beneath a gauze pad.

FIGURE 2 is a sectional view of the bandage shown in FIGURE 1, taken substantially on line 2 2 of FIG- URE 1.

FIGURE 3 is a perspective view of another adhesive bandage embodying the features of the invention having a pouch containing medicament disposed toward the pad.

FIGURE 4 is a sectional view of the bandage shown in FIGURE 3, taken substantially on line 4-4 of FIG- URE 3.

FIGURE S is a perspective view of another modified adhesive bandage embodying the features of the invention wherein the pad is saturated with medicament and sealed from atmosphere.

FIGURE 6 is a sectional View ofthe bandage shown in FIGURE 5, taken substantialy on line 6--6 of FIG- URE 5. v

FIGURE 7 is another sectional view of the modified bandage shown in FIGURE 5, taken substantially on line 7--7 of FIGURE 6.

Referring now in detail to the accompanying drawings which illustrate exemplary embodiments of the invention,

and particularly to FIGURES 1 and 2, the bandage in-v cludes a strip 11 of thin material, preferably plastic, having an adhesive coating on its under surface, and to the medial portion of which there is attached an absorbent pad 12. The projecting end portions of the adhesive strip 11 normally are protected by layers 13 and 14, one of which is of sufficient length to overlay the bottom surface of pad 12.

Beneath the pad 12, and adhesively secured to strip 11, is a pouch 16 enclosing a mass of medicament 15, which may be either a salve or fluid. The pouch 16 is formed of thin rupturable plastic material and may be scored on its upper surface, to direct the How of medicament upwards into the pad when pinched.

With reference to the embodiment of the invention shown in FIGURES 3 and 4, the medicament is contained within an envelope 26, formed by one end 27 of strip 21, and the upper surface 28 of the extended end is adhesively coated; or the pouch or envelope 26 may be laid upon end 27. The openable end 29 of the envelope 26 is directed toward pad 12.

In order to use the adhesive bandage, the pouch, 16 in FIGURES 1 and 2, or 26 in FIGURES 3 and 4, is ruptured by the application of finger pressure, as to release the medicament 15 in the direction of the pad, and the medicament adheres to or is absorbed by the pad. The protective layers 13 and 14 then are removed and the bandage applied to the skin in the customary manner. With referenceto the FIGURES 3 and 4 disclosure, where envelope 26 is merely laid upon end 27, once the medicament is released therefrom, the envelope may be stripped from the end when the protective layers 13 and 14 are removed.

Referring now to the embodiment of the invention shown in FIGURES 5, 6, and 7, the bandage includes a strip 31 of thin plastic material having an adhesive coating on its under surface, and to the medial portion thereof, spaced inwardly also from both edges of the strip, there is attached an absorbent pad 32, which is saturated with medicament 35, which may be either in salve or liquid form. The projecting end portions of the adhesive strip 31 are protected by plastic layers 13 and 14. One of the protective layers, 13, is formed, as by molding, to substantially conform to the surface of the strip and pad seated thereon, and comprises a strip engaging portion 40 and a pad engaging portion 41. Pad engaging portion 41 overlays and seals the pad 32 and medicament 35 saturated theren against the medial portion of t'he strip 31, and may also be provided with an upwardly extending lip 42 engageable to facilitate easy removal of the protective layer from the strip.

Where the embodiment disclosed in FIGURES 5, 6 and 7 is used, the protective layers are removed and the bandage applied to the skin in the customary manner.

With applicants bandage',` antiseptic or other medicament in an effective predetermined dose is applied in its freshest form and with the intended most beneficial therapeutic effect, and, in *comparison with other means of application, there are no bottles to break, no applicators to become lost, 'no sprays not capable of being directed to the wound and only to the wound, and no large amounts of medicament available to patients, particularly to children.

Although applicant has disclosed exemplary embodiments of the invention herein, it is to be understood that the description thereof is intended to be illustrative only, rather than restrictive, as many details of the structures disclosed may be modified or changed without departure from the spirit or scope of the invention. Accordingly,

it is not desired that I be limited to the exact constructions described, except as limited in the following appended claims, wherein I claim:

1. An adhesive bandage comprising a strip of thin material having an adhesive on one surface thereof, an absorbent pad attached to the adhesive surface on said -strip medially of its ends, protective layers of thin material adhesively secured to the end portions of said strip and at least one of which layers overlays the pad, a sealed enclosure containing a medicament integrally connected to said strip, said enclosure adapted to expose the medicament at a selected time.

2. The adhesive bandage recited in claim 1, in which the enclosure is rupturable to release the medicament onto the pad.

3. The adhesive bandage recited in claim l, in which the enclosure comprises a rupturable plastic pouch seated on the strip beneath the absorbent pad.

4. The adhesive bandage recited in claim 1, in which the enclosure is secured to one end portion of said strip adjacent the absorbent pad.

5. The adhesive bandage recited in claim 1, in which the absorbent pad and the medicament are contained within the enclosure.

6. The adhesive bandage recited in claim 1, in which the protective layers are removable to expose the medicament on the absorbent pad.
